Use of site-directed mutagenesis to identify an upstream regulatory sequence of sodA gene of Escherichia coli K-12.

Proceedings of the National Academy of Sciences of the United States of America - 1 Apr 1990

Naik S M, Hassan H M

Abstract excerpt

Mn-containing superoxide dismutase (SodA; superoxide:superoxide oxidoreductase, EC 1.15.1.1) biosynthesis in Escherichia coli is regulated by several environmental stimuli. The DNA sequence of sodA shows the presence of a potential binding site for a regulatory protein(s) at the -35 region. To explore the possible role of this region in the regulation of sodA, we used oligonucleotide-directed site-specific...
